Comment (by eschnett):

 No, the last output iteration is stored globally, and at each iteration,
 output occurs for each refinement level that is active at this time.
 Otherwise, you would receive too much coarse grid output, and coarse grid
 output would occur at times when finer grids are not output. The behaviour
 has nothing to do with refinement levels.

 If you specify a reasonable out_every, the behaviour is what you expect.
 If you specify an unreasonable out_every, Carpet will round up to the next
 reasonable value. The divisor method will instead disable output. Both
 choices are easy to understand.
